This invention relates to mechanism for windingmaterial uponairoll andmore particularly to means for deta'ehahly and rotatably mounting the"roll. a

i; 'Thegeneral object ofj thr inventionis'to provide neans to supportthe roll while the P mit material is beingwound thereonand the'ffullroll to 'be readily removed. a

The V object of the invention is I fill to-v mpr ovidea roll which isdriven by me of its gudgeonorshaft and which may beread- V ily detachedfrom its driving means to remove a 1111 roll'and permit replacement ofan empty roll;

The object of {the invention is further to provide an improvedconstruction by means of which the" driving shaft has a transverselydetachable interlocking connection with a 'gudgeon o-n'theroll. I

A'cloth roll 1 is'rotatably supported in the loom by m'eans o1": thefrarne members 2 and 'with an intermediate gear 8 which is driven fromthe usualtakeupmechanism,- any other the'cloth' from -the roll while itis still injthe loom which 'is a costly waste of "time, The

rollis novel andunder, normal running con- 3 iditions 1s a positlvedriving connection'but is constructed so that itgmay be d sconnected.

To accomplish this result the usual shaft or gudgeon on the clothrollat. the driving? end nalled atone end in a bracket10"secured-to" anda semi-cylindrical tportion removed 9 so that when these two ends areengaging and in proper driving relation they form a [continuouscylindrical section of shaft which turns inthe journalthus providing aposifdrive the roll without departing frOm the I is made in two parts.short shaft 9 is jourtive driving connection, between I the shaft 9 andthe-r011 I. 'The 'particular'shape of the interengaging ends of theshaft and gudgeon however is immaterial and any suitable constructionmay be used within the scope ofthe accompanying claims.

The journal 11 is made in two sections one section 15 of which is formedintegral with the frame member 3 and the other section 16 of which ispivoted thereon at 17 to swing from closed to open position. As clearlyshown in Fig.3 the gudgeon 14 is transversely detachable from the shaft.9 permitting. its ready removal when the movable section 16 of thejournal 11 is swung into openposition. A short length of the journal 11is in the form of a closed bearing 18 which embraces the cylindricalportion of the shaft 9 adjacent to its mutilated inner end. The purposeof this bearing is to retain the shaft 9 in proper alignment when thejournal is opened.

The movable section 16 of the journal is locked in closed position bymeans of a manually operable eccentric locking member 19 which ispivotally supported at one end in an car 20 upon the member 16. Thepivotal means consists of a stud 21 having a portion 22 which rotatesconcentrically within the ear 20 and another portion 23 the axis ofwhich'is eccentric to the axis of the portion 22. The locking member 19is mounted upon theeccentric portion 23 and is keyed thereto byga pin.The member 19 also has a lug 2a thereon which is positioned to engagethe inner edge of an abutment 25 upon the frame member 3 when the partsare in locked position.

To unlock or disengage the locking means the arm 26 is raised whichcauses the lug 24 to bedisengaged from the abutment and due to thecombined effect of the eccentricity of the section 23 of the stud 21upon which it is mounted and the motion it would have if the twosections of the stud 21 were in axial alignment, the lug 24 assumesposition which will permitthe movable member 16 to open into theposition shown in dotted lines Fig. 2. To look the bearing the movablemember is swung up into engagement with the other member of the journaland the arm 19 is swungdown into the full line position'shown in Fig. 2.

Theother end of the roll is herein shown as rotatably supported in theframe member 2 in a journal 27 which is similar to the journal 11 withthe exception that the section of closedbearing 18 is omitted and themovable member 16 has an end'wall 28which closes the end of the journalto prevent endwise movement of the gudgeon 29 and the roll 1. While thegudgeons 14 and 29 may be fixedly secured in the rolls they-arepreferably removable from the roll and may therefore be employed asbearings for different rolls. Furthermore the removability of thegudgeons shortens the effective lengthof the are recessed and leafsprings. 31 are mounted in recesses and project beyond the surface ofthe gudgeons in such a manner as to engage the ad acent walls of thesocket thus increasing the friction between the gudgeons and the wallsof the sockets.

As previously stated the roll may be driven in any manner but by way ofillustration we have shown generally a frictiondrive which automaticallycompensates for the varying diameter of the roll asthe cloth is woundthereon. The gear 7 is fixed to one member 32 of the friction device andis freeto rotate upon the shaft 9 and frictionally engages the member 33which is secured to the shaft 9 and is releasable therefrom. If it bedesired to rotate the roll manually independently of the driving gears alever 35 is provided to disengage the frictional connection between themembers 32 and 33 at which time the roll may be rotated by means of thehand wheel 34 which is a part of the member 33.

' When the roll 1 becomes filled it is a simple matter to remove it fromthe loom and replace an empty one therein without disturbmg any part ofthe mechanism. The two journals are unlocked and swung open which ingsto receivethe shaft or gudgeons of a roll and to permit removalthereofsubstantially horizontally in a direction normal to the axis ofsaidbearings, a driven roll-actuating shaft extending into one of saidbearings, a roll having gudgeons fitting said bearing and detachableinterengaging means upon the ends of said driven shaft and the adjacentgudgeon retainedin interengaging relation by the bearing embracing themwhen said bearing is in closed position.
